Weather report, W. H. Day (Ann. Rpt. Ontario Agr. Col. and Expt. Farm,

 season, wind, and damage by lightning at different places in Ontario for the 

 year 100!) are reported. 



[Meteorological observations in Trinidad] {Ann. Rpt. Dept. Agr. Trinidad 

 and Tobago, 1908-9, pp. 19-24). — Tables give the annual rainfall at the Royal 

 Botanic Gardens, 1SG2 to 190S; mean annual records of barometric i)ressure, 

 temperature, relative humidity, and rainfall, ISSS to 1908; sunshine records, 

 1908; observations on barometric pressure, temperature, humidity, rainfall, 

 etc., at St. Clair, 1908 ; and annual rainfall for the Island of Trinidad as shown 

 by observations at GO different stations. 



The weather of the past agricultural year, F, J. Brodie {Jour. Roy. Agr. 

 Soc. England, 10 {1909), pp. Jf06-.'il f,) .—The general character of the different

 and observations indicating earth movements at Lake Victoria, are also 

 reported. 



The period of deficient rainfall which began in 1896 was broken in 1908. The 

 improved facilities for studying this subject are described. " During 1908 

 rainfall was measured at 88 stations in the Nile Basin while that recorded at 

 118 other stations in neighboring regions was studied in connection with the 

 meteorological conditions of northeastern Africa." Also, see a previous rei)ort
